Specification of `I,.V|ette rs ,Patent ol 9115, dated September"12,1838.`

To all whom t may concern.: i

Beit known that I, Primo PENFinLD STEWART, of Hudson street, in the city, county, and State of New York, stove maker,

have invented and made certain new ,andV

useful Improvements or Arrangements in Manufacturing Steves, which collectively designatev `as,"Summer and Winter Cook` ing-Stoves, using either wood or coal as fuel, and" for which improved arrange'-` ments I ask Letters Patent of the United States as not havin h y such lformiand combination and with such effect before my invention of rthe same, and

that the mode of `eonstructiing and usingV the said'improvements and the advantages intended to beattained thereby are `fully and substantially set forth andshown in the following description and" in the drawings attached to and making a part of this specie` iication', whereinf Figure 1. is a sectional side elevation,` Fig. 2. is aV sectional elevation of the `fire door end. Fig. 3. isa like elevation of the oven door end, and F ig, 4is a horizontal plan of `a"stove of this` arrangement and construction.

`The other detached figures are consecib i tively explained hereafter, and the like figures and letters, as marks of reference,

`applyV to the saine parts in all the several figures.

a, is the bottom plate. b, b, are two side plates. a

e, is the fire door end plate, made double belowA the door, at the endv of the oven. 01. is the fire door, made single or double, as may be chosen. i

d, is the oven doorend plate, Z1 is the oven door, also made double or single. f

e, in detached Figs. 5 and 6,- is a top plate to cover the ii-re; with openings, in which to place ,cooking vessels, made so as t0. give space, to two er more small vessels,

or to change and receive one ormore large f vessels. v

f, is the hearth with a top slideg, as a cover, and a bottom slide L, to empty the an. A A is the fire place or chest, shown open in'plan,Fig, 4, having `its'bottonfi z', flat, and

' sidesz'l, formed narrower below than at top,

as shown seot-ionally, by dotted linesu in Figs. 2, 3,` and 4.

lc, is the fire frate for coal or wood fuel,

i. .having the @endl-G5761 0.11. .each .Side returned been iliade or used in i i outward toward the top of '51,' as shown in out, by lifting directly out through the opening made by the shiftinV top plate, or by sliding endwise, on the anch lugs 7:22, shown inFigs. Vl, 2 and A3,by dotted lines.

l, is a damper or valve, on one side above plate b. The `plate `0, forms the, bottom of `the oven,V with theffiue o1 below it, and above this, on the other side,` the plate p, forms that sideof the oven, with the ascending flue p1 between that, and the out-` side plate Z). These plates, and flues, are `s hown direct, and seetionally, by dotted lines, in Figs. 2, 3 and 4.

ful.'

' i", is a soot valve, to clear the iue 01.

s, is a plate, forming a jacketing piece, under the bottomplate a t, t, are jacketing pieces on the sides b, b, made movable, by hinges and catches, or any convenient means. fu, is a jacket, on the oven door end, made either fixed or movable as may be chosen.

All these jacket pieces are to be of `tin or other bright metal.

g, is a chimney flue, leading as` need- `In Fig. 8 a shifting Hue piece u, going through the reservoir or boiler fw, which is fittedwith three cocks 1, 2, 3, and a supply cover `4 shown in plan in Fig. 9.

In Figs. 10, Il, y, is the upper, and w, the

lower, of a `double sliding plate, to use with Y wood fuel; in these, the openings 5 andI 6, are eounterpositioned, sothatA when the lower plate is in place, on the flanch lugs 7a2 and the upper one, y, on it, the draft through the fire, may be regulated or shut off altogether by sliding the plate y, farward, teward the door, which will bring the metal parts in y, either partially, 4or entirely over the holes inA and thus decrease, or shutoff the draft, and the valve h1 in the ire door, partially or entirely closing the opening below the lire, (will assist tol regulate the'draft, or if the fire door be a little shortened, and the hearth meant tobe used by sliding them in upon lugs, x1 in the oven, and thereby regulate the heat within the oven by intercepting the heat, radiated from the bottom and sides,Y t, and l of the fire-place, and in the space',`

between the tire place, 1` and flue, nl valve may be placed, as shown by r1 to intercept the main heat radiated'from the upper part of the descending Hue, af, 'and thus regulate, and decrease the heat 1n the oven when needful, and a small wire frame to keep the articles, baking, fro-m touching the bottom of the oven, will eectually pre- Vvent their being burntby the heat of that art. P I do not intend to confine myself to the particular mode described, of ittingvthe lire grate into the fire place, or forming the ref p-lace, as a square, or inverted semicircular form, will be the same in effect; the grate may be used, eitherY with, or without the risi ing returned flanches, at the sides, and with, or without, a lining of steatite, or soap stone, or Vof fire bricks, as may be found needful, according to the strength of fuel employed. Neither do I intend to confine myself to the sizes, or proportions, shown in the drawing, but to vary the same according to circum# stances. Neither do I intend to confine myself to any specific mode of mounting, or attaching the jacketing pieces, but to vary all, or any of the above described parts, in any manner, substantially the same, in the operation effected, and the results obtained.

The advantages intended to be attained by this combination and arrangement are as follows: First. By using the stove in the winter, with the jacks removed, a large amount of heat will be radiated off, and warm the apartment, or dwelling, with considerable effect, by a small increase of fuel consumed; and by using anthracite coal, the warmth may be maintained through the night. Second. By using the stone with the jackets on to confine the heat during sumf mer the apartment or dwelling, will not be uncomfortably heated, and the same amount of cooking can be done with a less consumption of fuel; and these two changes may be made daily if needful, during the variable weather, thereby, offering a ready mode, for equalizing the general heat for cooking, and the warmth of the apartment, or dwelling. Third. By the position of the hearth pan, with its top and bottom slides, the ashes may be at all times removed, without raising an oensive dust. Fourth. YBy the form of the fire place, and the position of the grate, or plates within it, so large a portion of the heat, generated, is radiated by the sides and flues, that the oven will be made hot for use,

by a very small expenditure of fuel; while, from the direction of the radiations, the articles in the oven will be operated on equally all around, without the tops being scorched, as would be the case, if the heat were strongly reflected Adirect from that part vwhich forms the bottomof the fire place.

Fifth. That, from the position and form of the fire grate, either mineral or vegetable fuel, or both, may be used on it, when required, and the heat, and consumption, be

lregulated by closing, or opening the valve, f/L, or the top slide g of the hearth, or by closing, or partially opening, the chimney valve Z. SiXth. That, by shifting out the fire grate in summer, and substituting for it, the double sliding plates, y, and m, Figs. 10, and 11, woodV orrpeat fuel maybe used,

' and the'draft through the holes 5, Y6, be so fully regulated, that almost any increment or decrement of heat maybe obtained, and when' the object is effected the plates may be slid so as to. close the holes 5, 6, on which the firewill go Vout ,but the fuel willremain in place, ready for reignition in a few minutes, thus avoiding, either'dust, or, loss of time, or waste of fuel, or the riskof fire,

by the disposition of the burning remainsl of the fuel.- Seventh. That when from otherY operations going on while requiring a strong fire, or from an. other cause, the oven Vmay become too hot or present use, the heat may be decreased, and regulated, by closing the y valve i, or using the sliding plates, or both combined, to intercept the main strength of heatradiated from above. Eighth. That by using the covers y', in any season, the operations of broiling food, or heating flat irons, may be carriedon without such radiation of heat, as shalleither increase the consumption of fuel, or cause an uncomfortable accession of heat in the apartment or dwelling. Ninth. That by attaching the reservoir or boiler with the apparatus described above, a considerable portion of the heat which would otherwise go off by the chimney flue, may be made available for maintaining a supply of hot water, almost always ready for domestic purposes. Tenth. That among the incidental advantages of this arrangement, the addition of a reflector to hang against the side plate, forming the hereby declare, that I do not claim to havev invented grates, flues, or jacketing pieces, or

any of the separate parts, except, as hereafter stated.

1. I claim the arrangement and form of the fire-place, as combined With, and acting Within the oven, and the arrangement and action of the heating fines, as described in combination With the fire-place, and oven, irrespective of the form of the sto-ve in Which the said arrangements may noW, or hereafter be combined, and used. Y

2. I claim the general combination and arrangement herein before substantially detailed and set forth, under any variations of the proportions which do not cause an y alteration of the general effects; and advantages produced by said combination, and arrangement, and the methods of using the same, as herein set forth, which collectively form the summer and Winter cooking stove, for which I seek Letters Patent.

In Witness whereof I have hereunto set my hand, in the city of New York, this sixteenth day of Ju1y,ione thousand eight hun# dred and thirty eight.
